(c) Assume current real GDP falls short of full-employment output by $500 billion and the MPC is 0.8. (i) Calculate the minimum increase in government spending that could bring about full employment. Answer to 1. (c) (i): The expenditure multiplier [ M E ] would be 5 [1/.2 = M E of 5]. Because current output The expenditure multiplier [ M E ] would be 5 [1/.2 = M E of 5]. Because current output falls short by $500 billion, it would take a minimum increase in government spending falls short by $500 billion, it would take a minimum increase in government spending of $100 billion to get to full employment. [5 X $100 = $500] of $100 billion to get to full employment. [5 X $100 = $500] (ii) Assume that instead of increasing government spending, the government decides to reduce personal income taxes. Will the reduction in personal income taxes required to achieve full employment be larger than or smaller than the government spending change you calculated in part (c) (i)? Explain why. Answer to 1. (c) (ii): Because the tax multiplier [ M T ] is smaller, or [MPC/MPS =.8/.2 = 4], it will take a larger Because the tax multiplier [ M T ] is smaller, or [MPC/MPS =.8/.2 = 4], it will take a larger tax cut then the increase in government spending. Because current output is $500 bil. tax cut then the increase in government spending. Because current output is $500 bil. short of FE Y, and the M T is 4, it would take a tax cut of $125 billion. [4 X $125 = $500] short of FE Y, and the M T is 4, it would take a tax cut of $125 billion. [4 X $125 = $500] 3 pts – 1 pt – $100; 1 pt – larger Tax reduction; 1 pt – larger Tax reduction; 1 pt – smaller M T or not all increased Y spent. 1 pt – smaller M T or not all increased Y spent.

3. The PPCs for Artland & Rayland are shown. Using equal amounts of resources, Artland can produce 600 hats or 300 bicycles, & Rayland can produce1,200 hats or 300 bicycles. (a)Calculate the opportunity cost of a bicycle in Artland. (b) If the two countries specialize and trade, which country will import bicycles? Explain. (c) If the terms of trade are 5 hats for 1 bicycle, would trade be advantageous for each of the following? (i) Artland (ii) R ayland (d) If productivity in Artland triples, which country has the comparative advantage in the production of hats? Answer to 3. (a): Answer to 3. (a): The Domestic Comparative (opportunity cost) of a bicycle The Domestic Comparative (opportunity cost) of a bicycle in Artland is 2 units of hats. [1 bicycle = 2 hats or 600/300=2] in Artland is 2 units of hats. [1 bicycle = 2 hats or 600/300=2] Answer to 3. (b): Answer to 3. (b): Rayland will import bicycles. Domestically, they have to give Rayland will import bicycles. Domestically, they have to give up 4 hats to get a bicycle but with trade they have to give up up 4 hats to get a bicycle but with trade they have to give up only 3 hats. only 3 hats. DCC: Rayland DCC: Artland 1 B = 4 H 1 B = 2 H ¼ B= 1 H ½ B= 1 H Terms of Trade Terms of Trade 1 B = 3 H 1 B = 3 H 1/3 B = 1 H 1/3 B = 1 H Answer to 3. (c) (i): Yes, 5 hats is better than 2 hats they are getting domestically. Answer to 3. (d): 300 bicycles would become 900 and 600 hats would become 1,800, so the Answer to 3. (d): 300 bicycles would become 900 and 600 hats would become 1,800, so the DCC would still be 1 bicycle = 2 hats, same as before. Rayland still has a C.A. in hats. DCC would still be 1 bicycle = 2 hats, same as before. Rayland still has a C.A. in hats. Answer to 3. (c) (ii): No, Rayland is going to export hats so opportunity cost is ¼ bicycle. So 1/5 of a bicycle would not benefit them. 1 pt for “1 B = 2 H” 2 pts for “Rayland will import bicycles” 1 pt for “Yes, 5 H is better than 2 H” 1 pt for “No” 1 pt for “No change, so Rayland still has a comparative advantage in hats”
